About
Sonic is a real-time text-to-speech model built for voice agents, combining natural delivery, sub-90ms latency, and native support for more than 40 languages. It is designed to make voice interactions feel effortless, with tone that adjusts to context, consistent pacing, and speech that follows the natural rhythm of conversation. By default, Sonic interprets the emotional subtext of a transcript and calibrates delivery automatically, while non-verbal expressions such as laughter can be inserted directly into the text. The model follows transcripts faithfully, produces clean audio across languages and voices, and handles alphanumeric content such as order numbers, phone numbers, IDs, and email addresses naturally without preprocessing. Context-aware pronunciation helps heteronyms sound correct from surrounding words, while custom pronunciation dictionaries let teams define how proper nouns and domain-specific terms should be spoken.

About
Language Reactor is a freemium browser-based language learning toolbox available via Chrome (and Edge via browser compatibility), designed to transform authentic media into effective learning content. It injects dual-language subtitles when watching Netflix and YouTube, allowing users to see both their target and native language, paired with a hover or click pop-up dictionary for instant definitions, synonyms, and pronunciation. The extension supports importing text and e-books, adding machine translation overlays and realistic text-to-speech, making static content dynamic and interactive. It includes tools like PhrasePump, a listening-exercise module, and a chatbot for conversational practice, in addition to word-list management, color-coding words by familiarity, and playback controls that include auto-pause, speed adjustment, and sentence looping to reinforce comprehension.
